Jeon Jungkook is the youngest member of the 7 member Korean boy band which is BTS or 방탄소년단 (Bangtan Sonyeondan). BTS is also a popular boy group worldwide and widely support and love by their huge fandom which  is called ARMY or Adorable Representative M.C for Youth. These fans is also known for their broking so many records for their boys. So as a matter of fact even in Pandemic they gave JK a suprise gift by wrapping the entire 400 meter long KTX (Korean Train Express) of congratulatory message for his birthday. 

I am so amazed to Twt @Jungkook_China for this awesome gift ever.
